Continued excavation and investigation of blocklifted lorica segmentata

13 Hydref 2011

Just a short blog entry today, describing the completed excavation of another area of the soil block, and some of the interesting features that have cropped up.

This section of the block is composed of what appears to be two flat lorica plates, one lying at a 45 degree angle to the other. Note the length of the straight edge of plate; I believe that this plate will be one of the large plates that came across the middle of the cuirass. I have included annotations indicating small areas of potential importance, such as the corroded remains of fittings (see red arrows), which stand proud to the surface of the plates. The gap between the plates, which shows how damaged and broken the edges of the lorica set really are, can be seen in the second picture.

I have found another fragment of plate with a rolled edge (see third photograph), though the roll itself is much narrower in comparison with that exposed within the girth hoop (refer to previous blog entry). The fragment itself is also a little too small to detect any curvature or to easily extrapolate a larger shape, but could this fragment be part of a plate (the breast or backplate) that would have been in contact with the wearer’s neck? All comments and opinions regarding this little hypothesis are welcome.

I have included a macro shot of a small cylindrical item: whilst this may be physically unimpressive, I believe that this could be the iron pin that would have been drawn through a lobate hinge, holding the shoulder plates together.

As mentioned above, obvious fittings that are immediately identifiable still haven’t been found, and careful excavation has only managed to produce vague shapes of what is essentially metal corrosion. I have included in the last photograph a view of an area of probable lorica attachments and fittings, though only a very good quality x-ray will be able to make any sense of these lumpy features.

As a last aside, I thought I should provide a brief explanation for the condition of the buried lorica segmentata. Readers may have noticed how exposed finds lack the thick crusts of rust and voluminous corrosion products typical of a lot of archaeological iron objects: this is most likely because the thin iron plates corroded extremely quickly, with the iron leeching into the soil. Whilst this does mean that I will not have to spend hours removing powdery iron corrosion in order to reach a more certain surface on the iron, it also indicates that the remaining ‘object’ is more of a pseudomorph lying on top of the soil: this is why the ‘plate’ most often does not respond to the pull of a magnet. This level of deterioration will have implications for the eventual conservation treatment of the armour, as I may be unable to extract the iron plates (which have very little physical integrity), from the soil. 

Big Draw

Sian Lile-Pastore, 10 Hydref 2011

Hello!

Every year we take part in the Big Draw Here are the pictures from this year which took place on the 1st and the 8th October. We made a paper version of St Fagans: National History Museum inspired by Made by Joel, and used some of his images too.

Excavating a Girth Hoop

5 Hydref 2011

To the right is an image of the lorica segmentata girth hoop, complete with a copper alloy tie ring, after excavation in the conservation laboratory. The general shape of the hoop, which is lying on its side, can be discerned, and it is obvious that the plate is broken in several places. I had hoped to be able to see how the solid tie ring interacted with the girth hoop, but unfortunately too little of the iron plate remains in a stable enough state to remove enough of the obscuring soil currently supporting it. An x-ray of this area of the block will show the complete shape of the tie ring, and hopefully how it is attached to the plate.

 

To reiterate, I am excavating the artefacts in this soil block in the same way that archaeologists do in the field, and am coming across the same extraneous stones, silty-soil and common artefacts such as ceramic building material and animal bone contained within the burial deposit that are found on the average archaeological site. As the stones, tile, etc, do underlie so much of the fragile iron plate, I will not remove them at this stage, though I am aware they could be covering more artefacts.

 

Within the hoop further broken plates can be seen, most notably a flat plate with a rolled edge: this is one of the few plates that can at this early stage be attributed to a specific area of the cuirass; the only plates with rolled edges were the lowest girth hoop above the hip, and the breast and back plates. Given the flat nature of this plate, it is most likely the lowest girth hoop.

 

To give readers an idea of the depth of the archaeological remains in the soil block, I have included photographs of the back of the girth hoop, as well as a photograph showing the interior. Of interest in the third photograph is part of a plate held to the back of the girth hoop by corrosion and burial products, and how thin the lorica plate with a rolled edge is in the fourth.

 

Not all artefacts excavated in this area of the soil block can be as easily identified as the plate with the rolled edge; some of the iron has suffered greatly, and only vague shapes in the soil can be distinguished. Removing soil from the surfaces of these mineralized objects has been challenging, as I have to be careful not to take away any burial deposit that might contain corrosion that may be part or all that is left of the archaeological object.

 

I have not recovered as many fittings, such as buckles, rivets, washers and studs as those found on cuirasses from other Roman sites, and it will be these attachments, and their position on the body armour, that will be very important when trying to work out which plates were breastplates, backplates, shoulderguards, etc. As expected, I have not found many of the valuable copper alloy fittings which could have been removed for re-use during and after the occupation of the fortress by military forces, although I have found possible iron components, harder to spot given the corroded nature of the metal. For example, in the last photograph, the red arrows are pointing towards vague rectangular shapes slightly proud of what is an extremely fragmentary lorica plate; these might be the remains of fittings. Again, only high quality x-radiography will provide us with an image which might allow curators to make an identification of what these deteriorated artefacts are.

 

The hoop and other items will remain in place until the rest of the block has been excavated, when deconstruction will take place.

Join us at Quilt Club

Sian Lile-Pastore, 16 Medi 2011

I love quilt club, I really do. And if any of you would like to come along then I'm sure you will love it too!

It's a friendly, informal group and we get together and sew quilts! Quilter, and all round wonderful person Samantha Jenkins is on hand to help out if you get stuck or to help you get started if you have never quilted before. We meet every two months on a saturday morning at 11am until 12.30pm, the next meeting is on November 5th and is open to all - but please book your place by phoning 029 2057 3424.

Here are some pictures from recent meetings... I know there are more somewhere in the depths of my computer, so I'll have a hunt for those too.

Looking at Buildings

Sian Lile-Pastore, 16 Medi 2011

On Wednesday Ysgol Gynradd Gymraeg Evan James took part in the art activity that I offer to schools called 'Looking at Buildings'.

The pupils have a look at the buildings in the museum and make sketches of them, before returning to the activity space to create a 3d model. Here are some pictures of the wonderful work made.

If your school would like to take part in something similar, have a look here for more details.
